Si (Silicate) Profi-Test

Silicate occurs in tap water or purified water when the reverse osmosis or de ionizing unit is not functioning properly.
Silicate can result in diatom bloom and can block some essential trace elements such as vanadium and molybdenum.
The Salifert Test kit for silicate is a very fast, sensitive and accurate test, with two scales: an ultra low scale which is particularly useful for marine water and a high scale which is suitable for freshwater environments.
Sufficient for 60 tests.
Can be used for marine, fresh and garden pond water
